Hmm. Disney's pretty well-known for "touching up" their old films too, so I have a feeling this won't exactly help much in regards to getting the original versions. I mean, that's if Lucas doesn't have a specific in this deal prohibiting such a thing.
Also... yeesh, episode 7. We just have to keep going, don't we? I for one was holding out the smallest hope that at least, despite all the terrible Star Wars shit of late, that the live-action, episodic film franchise was mercifully done before it was run into the ground any further.
On the other hand, though, this does have two positives/potential positives I can think of: without Lucas at the helm, they might stand a chance of actually be good, a la Gene Roddenberry's "creative consultant" gigs. Also, I can't wait for the reporters to start zeroing in on Lucas's statements of the past decade in regards to Star Wars being and having always been this six chapter story of "The Tragedy of Darth Vader." Mm-hmm. Yeah, how is episode 7 going to fit into this? Is Darth Vader coming back as a ghost for more "tragedy"?
